ATTACHMENT TO SEWING-MACHINES.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, DAVE) CoeHILL, a subject of the King of GreatBritain, residing at Toronto, in the county of York and Province ofOntario, Canada, have invented a new and useful Attachment forSewing-Machines, of which the following is a specification.

My invention relates to a device adapted to be attached to any ordinarymachine, or a sewing machine adapted for special work such as corset orfancy sewing, whereby a strip or strap of tape may be attached to agarment by being sewed thereto and stitched along the outer edgesleaving a space between the rows of stitching to permit the msertion ofa stiffener either while being sewed to the garment or afterward.

The attachment consists essentially of a supporting arm adapted to beattached to the head of the machine and extend upwardly over the head ofthe machine, and be provided with a series of supporting shafts adaptedto carr spools, on which the tape and stiffener to e sewed to thegarment are carried.

Carried by pivotal supporting arms at-:

tached to the head of the machine and adapted to extend in front of thehead immediately below the upper end of the supporting arm on alinement,is a folder which consists of a flattened tube, the lower end beingcurved and adapted to direct the strip of material also the stiffener toa position immediately in front and very close to the foot and needle ofthe machine. The upper end of the folder is open and flared and isformed with wings adapted to turn the outer edges of the strip ofmaterial inwardly in the course of passing down through the tube to thepoint of egress.

I attain these objects by the device as illustrated in the accompanyingdrawings in which;

Figure 1 is a perspective view of a sewing machine with the attachmentin position; Fig. 2 is a front elevation of the folder; Fig. 3 is a sideelevation of the folder; Fig. 4 is a detail perspective view of theupper end of the folder, and Figs. 5, 6, and 7, are cross sectionalviews through the upper end of the folder on line M, 6-12, and 0c, Fig.4:, respectively. v

Like letters refer to like parts throughout the specification anddrawings.

a designates a carrying arm preferably consisting of a curved strip ofmetal adapted to be fastened to the back of the head of a sewing machineand extend upwardly and forwardly. Fastened to the carrying arm andextending at right angles therefrom are supporting shafts b on'which aremounted rotatable spools 0, and on the spools are wound the stri offabric or tape adapted to be stitched to the garment.

In the illustration I have shown two spools carried by the supportingarms, but any number may be carried for difi'erent class work. portingshafts are adjusting collars d provided with thumb-nuts e by which theymay be adjusted to the supporting shafts for the purpose of readilyremoving and replacing the spools.

- f designates the folder which consists of a flattened curved tube openat both ends, the upper end f being flared or enlarged On the outer endsof the sup- Patented July 2.5, air.

and formed with wings g in each of its outer I edges, being adapted toengage with the outer edges of the strip of fabric or tape and turn theedges inward in the course of passing down through the tube. The wingsare formed by a section of the tube being slitted and folded in uponthemselves and extend from the upper outer end of the folder, downwardlyany convenient depth, a slight interval being left between the wing andthe side of the tube, so that a strip of material passing down betweenthe wing and the side of the tube will be directed and creased byengaging with edge of the wing. Extending downwardly from the upper partof the folder and in a position interposed between the two wings, is aflat tongue it formed by the slits by which the wings are formed, thepurpose of the tongue beingto press or hold the strip of tape flatwithin the tube and provide against buckling as the edges are beingturned up by the wings g.

Figs. 5, and 6, illustrate the relative position of the combination ofthe strip, tongue, and folder in the act of turning the edge inward.Fastened to the back of the folder fare connecting arms 2' and j bywhich the folder is adjustably attached to the head of the machine. Theconnecting arms are attached to the head of the machine by thumbnuts 70by which they may be'adjusted or removed. Formed on the outer face ofthe folder are a series of guide loops Z by which the stiffener orinter-lining may be directed down the outer face of the tube to thepoint of egress in the bottom of the tube through which the strip oftape or fabric passes. Formed through the front face of the folder is anelongated slot n by which communication to the interior of the foldermay be had for the purpose of getting at the strip of tape or fabricwithin the folder in the event of it getting twisted or stuck, and alsofor the purpose of directing it down through the tube when first beingconnected. The end of the tongue h is sllt to make the end pliable andalso to facilitate the passing of the tape or strip down through-thetube in the initial passage through the tube or folder. The upperconnecting arm 2' by which the folder is connected to the head of themachine is jointed, and adjustable by a thumb-nut Z, that the upper orfolding end of the folder may be adjusted away from or against the headof the machine to bring it in a proper positlon below the spool 0.

The operation of the devlce 1s as follows, the strip of fabric or tapeis wound around one of the spools 0 preferably the lower, and thestifl'ener or interlining the upper. The free end of the fabric or tapeis directed downwardly and forced into the flared upper end of thefolder, the outer edges engaging between the folding wings g, that theedges may be folded over upon themselves in passing down through theoutlet in the lower end of the folder. The free end of the stiffener orinterlining passes down through the guide loops Z and are adapted toengage with the folded strip of fabric at the bottom of the folder andpass under the foot of the machine and needle, by which the strip isstitched along the outer edges, and the stiffener or interlining inbetween the folded edges of the fabric. The strip or tape and thestiffener or interlining are regulated in passing through the folder bythe action of the needle foot and will be drawn in through the folder asrequired.

What I claim as new and desire to secure by Letters Patent is,

In an attachment for sewing machines, a curved flattened tube, said tubeopen at either end, the upper end of the said tube being flared orexpanded, folding wings formed integral with the inner sides of theflared upper end of the said tube, a flexible slitted tongue .formed inbetween the said folding wings in the said tube, guide loops formed onthe outer face of said curved tube, connecting arms formed with the saidtube, said connecting arms adapted to adjustably attach said curved tubeto the head of the machine, substantially as described.
